1

Microtia

part of the pinna is missing or deformed (outer ear disorder)

2

Anotia

complete absence of pinna, common in individuals with Down Syndrome (auricle disorder)

3

Otoplasty/pinnaplastry

procedure done to repair the pinna, just for appearance

4

Basal Cell carcinoma

most common form of skin cancer, result of too much ultraviolet light from the sun (auricle disorder)

5

Keloids

can be removed but may grow back, scar tissue development and it swells (auricle disorder)

6

Tumour

painless, slowly growing solid tumour that distorts the auricle and destroys the normal architecture (auricle disorder)

7

Cauliflower ear

caused from repeated blows to the ear, fluid and blood fill the space and harden, causing permanent deformity (auricle disorder)

8

Perichondritis of the auricle

complication of an ear-piercing, looks ready to burst, skin is red and warm

9

Auricular hematomas

caused by direct trauma to the pinna, torn perichondria vessel bleed between the detached perichondrium and underlying cartilage

10

Psoirasis of the external ear

itchy, flakey skin inside the ear (auricle disorder)

11

Bifid earlobe

earlobe is divided into two small sections (auricle disorder)

12

Supernumerary auricle

it does not affect hearing, just doesn't look ecstatically
appealing (auricle disorder)

13

Cerumen

causes a conductive hearing loss, affects localization of sound, loss of approximately 45dB for conductive hearing loss (EAC disorder)

14

Stenosis

narrowing of the body Canal (EAC disorder)

15

Atresia

complete blockage of the canal, loss of 60dB of hearing, this is when bone conduction picks up (EAC disorder)

16

Otomycosis

fungal ear infection (EAC disorder)

17

Osteomyelitis

infection of bone, the infection reaches the temple bone (thin wall) (EAC disorder)

18

Otalgia

ear pain (EAC disorder)

19

Furunculosis

infection of ear hair follicles (EAC disorder)

20

Perforation from trauma or pressure

rupture of the tympanic membrane, can occur from physical damage to the ear (high impact) or change of pressure (TM disorder)

21

Myringotomy

opening of the eardrum to drain fluid- surgeons use zigzag cigarette paper to repair the tympanic membrane

22

Otitis media

occurs in the mucous lining of the middle ear space, Eustachian tube is not functioning properly, fluid builds up and becomes infected (ME disorders)

23

Facial Palsy

muscles on one side of the face become weak or paralyzed - trauma to 7th cranial nerve (ME disorder)

24

Barotrauma

caused by an increase in air or water pressure (airplane or sub diving) (ME disorder)

25

Cholesteatoma

Onion like structure (tumble weed), interferes with the ossicles, must be surgically removed, but can come back (ME disorder)

26

Otosclerosis

originates in the inner ear, but makes its way to the middle ear. Causes conductive hearing loss, it affects the stapes - spongey like growth, footplate becomes fixated on the oval window, and this limits the vibration transmitted to inner ear (ME disorder)

27

Tympanoplasty

repair possibles or tympanic membrane, substitute metal or plastic prosthetic for damaged area

28

Stapedotomies

small, fenestra strapedectomies

29

Stapedectomoes

removal of the stapes, prosthetics replace it

30

stapes mobilization

stapes is broke, for off sponginess to stiffen it
